Step 5. It will pop up a small window to tell you the files on the USB drive will be erased. Please back up the USB beforehand.
Step 1 and step 2 are the same, just open “Windows To Go Creator” in the main interface, and select Creating Windows To Go with PC.
Step 3. Choose “Create Windows To Go with the current system, and you will see the elaborate information of the current OS on the computer, and click “Next”.

When the operation gets finished, Windows will be stalled on the USB. And you can insert it boot other computers.
Now, you can connect the USB to any other PC, and enter BIOS setup to set it as the boot drive. Then follow the steps below.
Step 1. With the USB inserted, turn on the computer.
Step 2. When the initial startup screen appears, tap the BIOS key (F2, F3, F4, F7, F8, it depends on the manufacturer that created the BIOS).
Step 3. And the BIOS setup will be launched. And use the arrow keys to choose the "Boot" tab.
Step 4. And choose "Change boot order", and move the USB to the first one on the boot sequence.
Step 5. Save the change and exit, and the PC will be started from the USB.
If you want to create a Windows creation tool (create a bootable USB for installation) you can refer to the following content and learn how to install Windows to your computer through a USB drive.
Step 1. Insert a USB drive into your computer and download the Windows ISO file.
Step 2. Click the “Search” icon on the left bottom, type “cmd” in the search box, and hit Enter to open the Command Prompt.
Step 3. Type “diskpart” and press Enter on Command Prompt to open the Disk part tool.
● list disk
● select disk n (n is the drive letter of your USB)
● create partition primary
● select partition 1
● format fs=ntfs quick.
After executing these commands, your USB is bootable for installation, and you need to burn the ISO file to the USB drive.
Step 4. And leave the Disk part tool, and open Command Prompt, then execute the commands as follow:
● xcopy A:\*.* B: /s/e/f”(A is the ISO image drive, and E: is the USB drive letter).
● A:\Boot\Bootsect /NT60 B: /force /mbr”.
The two commands will copy ISO files to the USB drive and write a bootloader to your USB. After that, you can use this USB to boot up your PC and install Windows.
